4 Claims.

The device forming the subject matter of this application is a means for oiling vdies ofthe kind used for cutting threads, and for similar purposes. 'I'he invention aims to provide novel means for carrying the oil, and for expelling ythe oil at the proper place, at the will of an operator. The invention aims, further, to provide a die oiler which will exercise its function properly,

y even though the handle of the die holder may not be in a vertical position.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the in-` vention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood thai*I changes inthe precise embodiment of the invention herein disclosed, maybe made within the scope of what is claimed, without departing from the spirit of the invention.

Fig. 5 is a cross section on the line 5-5 of Fig. 2;

Fig. 6 is a cross section on the line 6--6 of Fig. 2. f

Fig. 7 shows in elevation the oil expeller.

In Fig. 1 of the drawings, the numeral I marks a die holder, including a head 2 provided with a stem 3, the head 2 carrying dies 4, of the kind used for cutting threads, and for similar purposes.

'I'he numeral 5 designates, generally, a handle for the die holder I. The handle 5 embodies an inner member 6 and an outer member l. The inner member Ii has an enlarged portion B, and the outer member 7 has an enlarged portion 9. 50 The parts 8 and 9 are joined together b-y a threaded coupling Ill, toform an oil reservoir, designated generally by the numeral I I.

Figs. 3 and 2 show that the inner member 6 of the handle 5 has a solid inner end I2 which 55 is threaded into the stem 3 of the die holder I.

(Cl. lil-126) i In the inner member 6 there is a reduced cham,-v ber I4, communicating with the'. part 9 of the oil reservoir I i The oil reservoir- I IA is providedrwith a filling plug, marked by the numeral 3S.' outlet for the oil reservoir II is'supplied, and4 preferably is in the form of an angularspout' I5., mounted in the inner member 6 of thehandle 5 and communicating with the chamber I4." The outlet I5 is adapted to discharge downwardly or inwardly, between the front and rear surfaces of the head 2, upon the dies 4, and upon the workv that lis being `cut by the dies. A valve seatl is threaded or mounted yotherwise in the inner member Iil of the handle, at the outer end` of the chamber I4. In its innery end, the valve seat i6 has a recess I'Lshown best in Fig. 3. The valve seat IE is provided with any desired "nume ber of inwardly converging oil passages I3, come municating with the recess I1, and arranged around the axis of the valve seat I6, as Fig. 6 will show, when compared with Figs. 3 and 2. r

The numeral I9 marks an inverted cup-shaped cap, disposed in the reservoir' I l, and, specifically, f in the member 9 of the reservoir. At its inner. end, the cap I9 has an outwardly extended flange 20, which, with a gasket 2l, is bound between the ends of the reservoir parts 8 and 9, within the coupling I9. At its outer end, the cap l9`is-pro vided with an inwardly extended llange 22, vform-4 ing an opening 23 in the outer end of the cap I 9.

The numeral 24 marks an oil expeller, located in the part 9 of the reservoir II, and preferably'in the form of a tubular, resilient, metal bellows,- connected at its outer end to a concaved plate 25 secured to an outstanding ange 26 on a tubular plunger 21 disposed within the outer member 1 of the handle 5. Thevtubular plunger 2l slides in an annular yguide rib and abutment, which is carried by the outer member-'1 of the handlev 5, the guide rib and abutment being designated by the numeral 28.

A push button 29 is slidably mounted in the outer end of the part I of the handle, and has an axial vent port 39, in communication with the tubular plunger 2l. The vent port 39 is controlled by an outwardly closing check valve 3I, seated by a compression spring 32 in the outer end of the plunger 21, the inner end of the compression spring finding an abutment upon a cross pin 33 carried by the plunger 21. A compression spring 34 is located within the outer member 1 of the handle 5. The outer end of the spring 34 labuts against the push button 29, and the inner end of the said spring engages the abutment 28.

At 35 there is shown a valve, shaped to t in the recess I1 of the seat I6 and controlling the passages I8, the valve being carried by a stem 36 which is mounted for longitudinal sliding movement in the valve seat I6. The stem 36 of the valve 35 extends outwardly through the opening 23 in the cup-shaped cap I9, through the expeller 24, and into the tubular plunger 21, the stem being secured to the plunger by an attaching element 31, or in any other suitable way.

In practical operation, when the push button 29 is slid inwardly by an operator, the check valve 3l closes the vent port 30, under the action of the spring 32, and the spring 34 is compressed. The tubular plunger 21 moves inwardly, along with the push button 29, and the stem 36 moves inwardly also, the valve 35 being spaced from the recess I1 in the valve seat I6, as shown in Fig. 3, and the oil passages I8 of the seat I6 being opened. When the plunger 21 moves inwardly, the expeller 24 is compressed, and the cil is forced from the reservoir II, through the oil passages I8, into the chamber I4. The oil flows out through the spout I5, into the head 2 of the die holder I,- and lubricates the dies 4, and the work, in a way which will be understood readily by those skilled in the art. y

When the push button 29 is released, the parts assume the position of Fig. 2, under the action of the spring 34, and the valve 35 closes the oil passages I8.

The device is simple in construction, but it will be found thoroughly effective for the purposes hereinbefore pointed out, the construction being such that the operator can expel a slug of oil on the dies 4, even though the handle is not in the vertical, upright position of Fig. 1. When the push button 29 moves outwardly, responsive to the spring 34, the check valve 3| can open, to admit air through the port 30, thereby insuring a quick return of the parts from the position of Fig. 3 to the position of Fig. 2.

A die oiler comprising a die holder, a handle carried by the die holder and including a reservoir having an outlet discharging into the die holder, a valve controlling the flow of oil from the reservoir to the outlet, a compressible tubular expeller forming the top of the reservoir, a hollow stem connected to the expeller and constituting means for venting the expeller to the atmosphere, a portion of the stem being accessible to an operator,

lto actuate the expeller and to open the Valve, an
